Takara B. subtilis Secretory Protein Expression System

Overview

• Includes pBE-S DNA, an E. coli/B. subtilis shuttle vector containing the B. subtilis_-derived subtilisin (_aprE) promoter, secretory signal peptide (aprE SP), multiple cloning site (MCS) and 3` (C-terminal) his-tag sequence
• Supplied with SP DNA Mixture, a library of DNA sequences encoding 173 unique secretory signal peptides that can be inserted upstream of your target gene
• Fully compatible with In-Fusion Cloning kits and systems, allowing rapid and easy construct generation
• Includes B. subtilis strain RIK1285

More Information

Applications

• Optimize secretion by identifying the signal peptide which provides the highest level of expression of secreted protein
• The clone with the highest level of expression is then ready to use for scaled-up protein expression using B. subtilis

Components

Notes

• The B. subtilis Secretory Protein Expression System provides sufficient reagents for 10 library construction reactions.
• Genotype of B. subtilis RIK1285: Marburg 168 derivative: trpC2, ys1, aprEdelta3, nprR2, nprE18

Storage

• B. subtilis - RIK1285 glycerol stock: –80°C
• SP DNA Mixture and pBE-S DNA: −20°C
